CASI-I REGISTER.

. pplicatcn led `:December 8, 1923. Serial No. 679,380.

To all whom t may concern.'

Be it known that I, WILLY NAUMANN, a subject of Germany, and residing at Bielefeld, Germany, have invented certain new and useful Improvements in or Relating to Cash Registers, of which the following is a specication.

My invention relates to improvements in cash registers, and more particularly in cash registers of the type in which the printing mechanism is adapted toA beopcrated at will for giving out one or two checks or receipts by causing the same to make one or two revolutions, and the object of the improvements is to provide a cash register in which the printingmechanism is operated in such a wa that upon a single rotation of the printing mechanism one or two checks: or receipts are given out.

For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawings, in which the same reference characters have been used in all the views to indicate corresponding parts. In said drawings, 'I

Fig. 1, isa partial elevation of the cash register with the parts of the printing mechanism in the positions for giving outy one receipt,

Fig. 2, is a similary elevation sho wing a part of the printing andl paper feeding mechanism, the parts being in the positions for giving out two receipts, Y Y

Fig. 3,.is a similar elevation showing particularly the means for setting the paper feeding apparatus into position for feeding one or two checks,

Fig. 4, is a detail view showing the mechanism for cutting the strip of paper into checks,

Figs. 5 and 6, are detail views showing parts of the gearings intermediate lthe cash register operating and printing mechanisms, said gearings causing respectively one or two operations of the printing mechanism upon one operation of the cash register, and

Fig. 7, is a detail view showing the means for printing a record on a web of paper remaining in the register. i

To a shaft 1 a `gear wheel 2 is secured which is adapted to'transmit rotary movement .through the :intermediary o-f gear wheels 3, 4, 5, 6, 7 and 8 to a shaft 9 carryi ing twoy disks 10 and 11 .formedcwith cam grooves engaged by rollers 12a and 13a of levers 12am@ 18 having bifurcated ends st raddling the shaft 9. At their free ends prising a concentric portion 1021 extendingA over about two thirds of the circumference and an eccentric portion 1()b extending substantially over one third of the circumference, while in the disk 11 the portion ofthe cam groove which corresponds to the concentric portion 10L of the grooveof the disk 10 comprises an eccentric part 11b extending over about one third of the circumference, so that the groove of the disk 11 comprises two eccentric portions 11b connected by concentric portions 11a, 11a. Therefore the disk 10 isvadapted upon each rotation to impart a single printing movement to the member 14, while the disk 11 is adapted upon eachl rotation to impart thereto two printing movements. On a bolt 16 a bell crank lever 17 is `mounted the downwardly directed arm of which carries a pivot block 17a embraced bythe bifurcated part of a lever 18a of a roll measuring or cutting member 18 (Fig. 4). The upwardly directed arm of the bell crank lever 17 is formed at its end with two shoulders 17b and 17c cooperating each with two rollers 4?, 4a and 5a, 5a respectively mounted on the gear wheels 4 and 5. By thus providing two rollers 4a and 5'EL on each gear wheel 4 and 5 the roll measuring apparatus 18 is twic'e operated upon each operation of the cash register.

.Internally of the .cash register there 'are a setting member 19 rigidly connected with a cam disk 20, and a rock arm 21 mounted onf-,a bolt 21, as is best shown in Fig. 3.'

Substantially atthe middle ofthe said arm there'is a yroller 21a engaging in al cam slot 2()a of the cam disk 20 having a concentric and an eccentric portion. At its free or bottomend the lever 21 carries a' bolt 21b projecting outwardly through the wall of the casing and engaging in a slot 22a of an arm 22 rockingly mounted withfa slot 22b provided at its top endon a bolt 23. Near the slot 22' and at the right hand side the arm is formed with a nose 22C. rl`he bottoni end of the arm 22 is termed with a hook 22d adapted for engagement with a roller 2s@ of a rock arm 2li mounted on a shaft 25 and rigidly connected by sleeve with two similar levers 27 located so as to cover each other when looking from the side ot the inachine. and carrying at their ends a rubbe' roller 28 ntermi-ng a part of the mechanism tor teedl strip ot paper to the pr`nting mechanism.

On a` bolt 29 a bell cranklever 30 is mounted the bottom end oinv which cooperates with the nose 22c of the arm 229 while the upper arm carries a roller 30a bearing on a cam disk 5b rigidly connected with the gear wheel 5 by a Aspacing sleeve 5C. @n a bolt 3l a ,'leeve im is ino d the ends of which have vlrms ly secured thereto (Fig. 2). rlhe lever 33 is curved upwardly and its curved part engages the bolt 21h. The other lever El carries. at its end two rollers 3.4i and 34th supporting respectively the rods 12 and 13.

On the outinost type cylinder 35 et the printing apparatus a holder 36 tor an inl:- ing pad 37 is rockingly mounted. i biturcated arin 38 rockingly mounted at 38h engages a roller 86a otl the inking pad holder 36, anch substantially at its middle, it carries a roller 38a engaging in the cam groove of a disk 39 loosely mounted on a shaft 1li). rlhe shaft 10 carries a gear wheel e1 rigidly connected with the disk 39a a cani Vi2 cooperating with a printing toot lever and :i driving wheel Lie keyed or otherwise secured lto the shaft and adapted to transmit rotary movement to a gear wheel 4J? keyed to a 'lei-d roller i8 through the intermediary of gear wheels t5 and 16.v qWithin a paper guide t9 a strip1 of paper 50 is guided between rollers 18 and 28 to a knife 18.

The driving gear wheel e and the gear wheel are connected with a suitable gearing for transmitting intermittent mov .nent to the gear wheel 41, the cam disk 39 and the cam i2 tor moving and arresting the said parts at certain periods in the operation ot the mechanism. Mechanism of this kind is known in the art and has therefore not been illustrated in the drawing.

0n the shaft 40 a spool 59 having a strip of paper wound thereon is loosely mounted, and a strip of paper 51 taken therefrom is passed between the printing toot ida and inking pad 37 to a spool 52 for winding the same, the spool 52 being intermittently rotated by means of a paw] 53.

The operation oi the mechanism is as' tollows: lt may be assumed lthatthe setting member 19 is 'shifted two steps from the position shown in Fig. 1. The cam disk 20 connected with the setting member takes part in such movement andthe roller 21l is advanced relatively to' the cam disl: 2O through thel concentric part ot the cain slotwithout shitting the arm 22, which arm enibraces the roller 24a with its notch 22d, as is shown in Fig. 1. rlhe lever 12 remains in 'f2 gement with the roller li" ot the printing root lever Vfhen operating the cash register the 'cam disk 10 causes aA single printing operation or" the lever 1li. rl`lie feeding portion 418 ot the feed roller et? adrance-il the check strip a certain distance tor being cut by the knife 18, whereupon the roller 30a of the lever 30 leaves the concentric part of the cam groove ot the disl;v and the nose 22C ot the rod 22 is torced r wardly by the said lever, and the roller is rocked away from the feed roller i8 that the second feeding portion ot feed roller is inoperative and a single clic-rt;

given out, the second cutting operation oii .enit 18 being ineffective, because the .i olf pi r has not been advanced the tiret cutting oper tion. p

H5 however5 the setting member 19 into the position lV, the roller v21a moves within the eccentric portion of the cam groove 20 to the left and it throws the arin 22 by means ot the bolt 2lb out ot engagement with the roller 2e ot the 2d, is shown in Fig. 2. By rocking the lever 2lb to the left the lever 33 is forced downwardly and the lever 3e connected therewith is rocked upwardly, so that the rollers 3st and 34h litt the rods 12 and 13 so tar that the rod 12 releases the roller ldj and the rod 13 gets int-o engagement with the roller 14a.

Upon operation of the machine the cam disk 11 causes two printing operations to successively performed, and the ifirst and second. feeding portions 48a are operative because the notch 221 of the lever 22 is out ot engagement with the roller 24a, so that the roller 28 is relieved oit the pressure holding the same in engagement with the feeding disk 48. Therefore two checks having the same record printed rthereon are given out. y

`While in describing the invention reference has been made to a particular example embodying the same l wish it to be understood that my invention is not limited to the construction shown in the drawings1 and that various changes may be made in the general arrangement of the apparatus and the construction of its parts without departing irom the invention.
